I'm stuck in the same situation too.
Im doing As Geography Maths Psychology and Product Design (which i plan to drop)
So far im planning to do st john ambulance cadets, as well as tutoring boys with disabilities in the lower school of my school.
But thats all i have, i dont know what else can be done. If you can, tutor a young person with a disability id say give it a go. Its like creating your own work experience.
Good luck!
